David Henningsson, thank you for reporting this and helping make Ubuntu better.
As per http://www.dell.com/support/home/us/en/19/product- support/product/inspiron-13-7359-laptop/drivers?os=biosa an update to your computer's buggy, insecure, and outdated BIOS is available (01.06.00). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything? For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. Once the BIOS is updated, if the problem is still reproducible: 1) Please provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 2) Please make a comment specifically advising on if there was an improvement or not. 3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid. Thank you for your understanding. ** Tags added: bios-outdated-01.06.00 ** Changed in: linux (Ubuntu) Importance: Medium => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1548844 Title: Inspiron 13-7359: rfkill button has no effect Status in linux package in Ubuntu: Incomplete Bug description: Nothing happens when the button to enable/disable rfkill (a k a "airplane mode" or "wifi/bluetooth disable") is pressed. Most other buttons seems to work according to evtest although some of them has no effect (and the "switch video mode" button generates Alt-P). Some of the buttons generate messages like: [ 335.755925] dell_wmi: Unknown WMI event type 0x00: 0xe00c [ 335.755928] dell_wmi: Unknown WMI event type 0x00: 0x3 ...but the rfkill button is not one of them.
